A NON-HEMOLYTIC, GROUP B STREPTOCOCCUS INFECTION OF CULTURED BULLFROGS, RANA CATESBEIANA, IN BRAZIL

Abstract

A systemic streptococcal infection in cultured bullfrogs in Brazil was characterized by necrotizing splenitis and hepatitis with hepatic and renal hemorrhage. A non-hemolytic Group B Streptococcus appeared to be the cause of the lesions, and the stimulus for the splenic reticuloendothelial hyperplasia observed in the animals. Stress may have been a factor in the development of the pathological condition.
